A rocket-geek recollection on stoichiometry and flight-propellant reserve from Wayne Hale. The other day he tweeted that he’d been looking through his old files from Shuttle days and was wondering if there’d be a market for a book. I think there would be.

The Latest Email
I’m sure you’ll be as shocked as I am to learn that it reveals that she was very parsimonious with the truth.
Punishing Climate-Change Skeptics
In which my lawsuit (though not me personally) is discussed by my lawyers, in today’s WSJ. It’s now about sixteen months since we argued before the DC appellate court, with no ruling.
Commercial Supersonic
Here’s the latest entry. They seem to have persuaded Virgin into buying ten planes.
They don’t seem to be addressing boom, no mention of transcontinental flight. I have a lot of trouble believing they can do trans-Pacific non-stop. But I’d like to find out more.
Climate Prediction
What a concept. Read the concluding sentence.
An SLS “Explainer”
This is very disappointing, from Popular Mechanics. A real “explainer” would explain why SLS is not in fact going to get astronauts to Mars, and why “power” is not the most important figure of merit for a rocket. Instead, they just regurgitate BS from NASA.
Heading To DC
I’m in the air somewhere over Wyoming on the way to ORD to switch planes for a flight to DCA this afternoon. Attending a workshop on space safety tomorrow. I’ve got Internet, obviously, but what I don’t have is room to type comfortably, given the seat pitch and guy ahead of me reclining. So probably light posting.
Greenfail
So much for the 10kW-hr Tesla Powerwall.
Hillary Doesn’t Just Have An Email Problem
She has an NSA problem:
Now, over two months later, I can confirm that the contents of Sid Blumenthal’s June 8, 2011, email to Hillary Clinton, sent to her personal, unclassified account, were indeed based on highly sensitive NSA information. The agency investigated this compromise and determined that Mr. Blumenthal’s highly detailed account of Sudanese goings-on, including the retelling of high-level conversations in that country, was indeed derived from NSA intelligence.
Specifically, this information was illegally lifted from four different NSA reports, all of them classified “Top Secret / Special Intelligence.” Worse, at least one of those reports was issued under the GAMMA compartment, which is an NSA handling caveat that is applied to extraordinarily sensitive information (for instance, decrypted conversations between top foreign leadership, as this was). GAMMA is properly viewed as a SIGINT Special Access Program, or SAP, several of which from the CIA Ms. Clinton compromised in another series of her “unclassified” emails.
Currently serving NSA officials have told me they have no doubt that Mr. Blumenthal’s information came from their reports. “It’s word-for-word, verbatim copying,” one of them explained. “In one case, an entire paragraph was lifted from an NSA report” that was classified Top Secret / Special Intelligence.
How Mr. Blumenthal got his hands on this information is the key question, and there’s no firm answer yet. The fact that he was able to take four separate highly classified NSA reports—none of which he was supposed to have any access to—and pass the details of them to Hillary Clinton via email only hours after NSA released them in Top Secret / Special Intelligence channels indicates something highly unusual, as well as illegal, was going on.
You don’t say.
The SEDS Act
Dana has been talking about this for a year, but he’s finally introduced it:
To require the National Aeronautics and Space Administration to investigate and promote the exploration and development of space leading to human settlements beyond Earth, and for other purposes.
Development and settlement demand low cost of access to space, while NASA is forced by Congress to pursue a giant rocket that has exactly the opposite effect. I wish they’d left the E word out, because that’s implicit, and it allows people to maintain the status quo: “Well, the first thing we have to do is exploration, before we can think about development and settlement. And we can’t do exploration without SLS!”
I have a query in to Tony DeTora as to how this differs from the 1989 bill, because I still see no teeth in it regarding what to do if the administrator ignores it and doesn’t submit reports.
